Chapter 615 Backtracking

   "Yes, this is indeed your most advanced fighter. We are very satisfied with this fighter. Next, can we go to see the engine production plant?" Elder Lin asked.

   Driven by Qin Tao, they not only need to purchase advanced Su-35, but also need to purchase advanced AL-35F engines, so, taking this opportunity, they simply have a look at these engines.

  Simonov nodded: "Of course there is no problem. Next stop, we will arrange for you to visit the Salyut factory."

  The next day, Simonov arrived at the Salyut factory with visitors from the East.

   "Gentlemen, welcome to your arrival. We are very honored that our products are installed on fighter jets produced by the East. We hope to further promote the cooperative relationship between our two parties." Yeliseyev was very excited.

   "We are here to see the AL-35F engine." Mr. Lin directly explained his purpose.

   "Everyone, our factory does not produce AL-35 engines." Yeliseyev said very directly: "However, another engine we developed should be more suitable for you."

  Another engine?

  Everyone is a little curious.

   "It was developed by your factory, not by the Rurika-Saturn Design Bureau?" Qin Tao asked.

   "Yes." Yeliseyev said: "The thrust of this engine we developed has been increased to 13.5 tons, which is your best choice."

  Moscow is not only the capital of Da Mao, but also the residence of many design bureaus, as well as various production plants. The products of Rurika Saturn Design Bureau are mainly produced in two factories: Ufa Factory and Salyut Factory, of which Salyut Factory is in Moscow. It is also for this reason that Simonov brought Eastern guests to visit the Salut factory, but this factory does not produce AL-35F engines!

At the beginning, this factory was just a production factory, but after the collapse of the Red Empire, Yuri Yeliseev, the head of the Salyut factory, was ambitious. He decided to strengthen the design force of his factory, and even stayed The Rica-Saturn Design Bureau dug up a lot of people.

  This factory is already engaged in production and research and development. The first result of their research and development is the AL-31FN engine. This engine is specially exported to the East for the use of J-10 fighters.

From a technical point of view, the AL-31FN is not very difficult. It just made a single-engine adaptive improvement and transferred the external casing and other components. However, as a factory, it can have this capability. It's not easy anymore!

  However, they are not proud of it, they are still working on research and development, and the next result of their research and development is the AL-31FM engine!

   You can tell from the name that this engine is still based on the third uncle, but it is not easy to increase the thrust of the engine to 13.5 tons!

   "How did you do it?" Elder Lin asked curiously.

   "Yes, is this modified engine mature?" Qin Tao also asked.

   "Don't worry, everyone, our engine is very mature, and the main way we modify it is to increase the diameter of the fan."

  The turbofan engine is not complicated, it is equivalent to the core engine of a turbojet, and an external duct is added outside to drive the fan to blow air directly from the outside, so that it can provide more thrust.

  The larger the diameter of the fan, the greater the thrust, but at the same time, the greater the windward resistance. Therefore, it has become a common practice for fighter jets to use small bypass ratios and transport aircraft to use large bypass ratios.

The third uncle has matured. Now, simply increasing the fan diameter of the outer duct can increase the thrust of the engine, but the windward area will also increase. If the diameter of the engine changes too much, the entire engine compartment will have to be changed. The flow rate of the intake port must also be re-matched, which is a lot of work!

   "The diameter of the engine has increased from 905 mm to 924 mm. At the same time, we also plan to develop a new full-power digital control system." Yeliseyev said.

  The increase is only 19 mm, which is not too big, and it is completely acceptable. What's more important is the full authority digital control system!

The current third uncle uses a mechanical-hydraulic control system, which belongs to the control of the second-generation aircraft. This system is already outdated. You have to change with it.

  The benefits of doing this are too many. For example, directly using the radar's terrain mapping capability, or the low-altitude navigation pod, linked with the flight control system, can better fly at low altitude and high speed. When necessary, you have to climb up quickly at any time to avoid the front of mountains.

  If you only control the rudder surface and have no way to control the engine, then climbing is definitely not easy. If it is linked with the engine, then when you need to climb, you can automatically control the engine to increase thrust.

   It can be said that the inevitable road of engine modification includes the full authority digital control system. However, the modification of this system is not easy. Even the current domestic turbofan 10 and turbofan 15 are mechanical-hydraulic control.

   In this regard, Salut Factory is ahead of the times!

   "Your modification is very good. I just don't know when the modified engine will be finalized and equipped with troops?" Elder Lin asked excitedly.

   "At present, we still lack the necessary funds for the modification. As long as you can place an order to purchase our engine, we have research and development funds, and we can complete these modifications within a year or two."

   After talking for a long time, this engine has not been successfully developed yet!

  The enthusiasm of everyone suddenly cooled down.

"Everyone, our current modification technology is not difficult, and it will definitely be successfully developed. Moreover, we have a follow-up modification plan. After the first step is completed, the second step is to improve the geometry of the turbine and install a new nozzle. tube, so that the thrust of the engine can be further increased to 14.2 tons, and the third step is to increase the temperature of the turbine by 150K, and the low-pressure compressor becomes three stages, so that the thrust can exceed 15 tons.”

  Although Yeliseev is still trying to sell their plan, it is obvious that the big guys don't believe it. Salut is an engine factory, not a design bureau. Do they have this technical capability?

The next inspection was dull. The big guy looked at the production line of the engine, and saw that in some specific processes, technical workers wore a full set of space suits and entered the cabin filled with nitrogen to carry out welding work. All of this , are similar to the Age of the Red Empire.

   That evening.

   "What does Lao Maozi mean by this? He is unwilling to sell us the AL-35F engine, but only sells us the modified third uncle, and we have to pay for improvements?" Mr. Lin was very dissatisfied.

"We haven't seen more parameters of the AL-35F engine. We don't know how it achieves the 14.5-ton thrust target. If it is at the cost of sacrificing life, maybe this AL-31FM is also a good choice for us now." Qin Tao is quite open-minded.

  The thrust has been increased to 13.5 tons, which is already very good. It can greatly improve the performance of the existing aircraft. As for the AL-35F engine, Qin Tao is more worried about its lifespan.

After all, this engine was only used in the test of the Su-35. When it came to the new Su-35S, it used the brand-new 117 engine. This engine is said to be developed by combining the technologies of the fourth uncle and the third uncle. Yes, the performance is more advanced.

  The original AL-35F was eliminated. I don’t know the reason. It is likely that the service life is not up to standard due to the deliberate pursuit of thrust.

  At this time, upon hearing Qin Tao's words, Mr. Lin also seriously considered: "Are you optimistic about the improvement project in this factory?"

  Qin Tao showed a smile on his face: "At least their spirit is good. Mr. Lin, Damao now has so many companies left. Have you ever seen any company that has this kind of awareness?"

This is really an exception. After the collapse of the Red Empire, most companies are relying on their laurels, even for decades. Even the Sukhoi Design Bureau has lost its ability to innovate, and the Su-57 it produced, It's just a flattened Su-27, they never made a brand new fighter.

  Sariut is just an engine factory that produces the third uncle, but they are working hard to improve their research and development capabilities! This is really a special case, so that their research and development results have also attracted the jealousy of the Rurika Saturn Scientific Production Association. Deep development violated the intellectual property rights of the developing unit - the Ryurika Design Bureau, which has joined Saturn.

  The design power of a production plant is actually comparable to that of the Ryurika Design Bureau, and even later, they competed with their Ryurika Design Bureau for the engine of the Su-57. How can they not make their design bureau envious?

  Hearing what Qin Tao said, Mr. Lin nodded: "Yes, this Salut factory is indeed evil enough, so tell me, what should we do next?"

   Before Qin Tao answered, Mr. Lin's secretary rushed in: "Report, the superior's decision has been made."

   They came out to investigate this time, it was just an action of the Air Force, and the superior has not yet officially approved it! Now, during their visit, the superiors finally made a decision.

  Old Lin received the telegram, glanced at it, and his face suddenly became ugly.

   "What's going on? Didn't the superior approve it?"

Mr. Lin took a deep breath: "Yeah, 80 million dollars for one, even if we negotiated the price to 70 million dollars, plus various spare parts, and missile systems, one would cost 100 million dollars. Forty is four billion, and the superiors overruled it."

  The country is still too poor, and it is impossible to spend so much money all at once, even if the navy joins in with it, it will not work to share the funds!

  Going out to investigate is just an eye-opener. It is impossible to bring a batch of Su-35s there.

Thinking about it is also my own greed. Since the 1990s, the Air Force has never had a third-generation aircraft, but has hundreds of Su-27s, dozens of J-11s, and the J-10s that are starting to be mass-produced. The number is enough. Yes, the country has also invested a lot of money for this. After a few more years of delay, the purchase may be successful, but now, it still does not have the strength.

"However, we can't explain to Lao Maozi like this. If we directly say that we don't want to buy it, Lao Maozi will definitely be furious, and will even continue to investigate our J-16's infringement. If it is really unpleasant, it will not do us any favors. There are too many benefits." Elder Lin began to worry about this again.

"Hey, it's been a waste of work this time." Hearing the news, Qin Tao was also a little speechless. Although the current Su-35 is not the later Su-35S, after all, its airframe structure is still fine. Kong’s soft bone disease is different from the Su-27. If the Su-35 is brought back, the domestically produced J-11 will be able to take it to another level.

   Now, this plan is about to fall through.

   These things have nothing to do with Qin Tao, who builds warships, but who makes Qin Tao more capable? If this kind of matter is to be resolved satisfactorily, Qin Tao needs to make suggestions.

   "Of course we can't say that we don't buy it ourselves. We have to prevent Sukhoi from selling it to us, and we have to owe us favors." Qin Tao said.

  Old Lin's eyes lit up: "Quickly tell me, what should I do?"

   “Just go and spread some rumours.”

   Now, it is not easy to buy Su-35, but it is much easier to mess up the business.

   "Report, Simonov sent someone to invite us to the banquet." At this moment, another adjutant came in to report.

   "Okay, tell them we'll be right there."

The dinner was held in the banquet hall of the famous President Hotel in Moscow, and it was considered the highest standard of reception. After all, if Dongfang purchased forty Su-35 fighter jets this time, it would become another member of the Sukhoi Design Bureau. A major arms sales project, but also a major arms sales for Da Mao.

"Welcome my Eastern friends, I remember very clearly that before and after the collapse of the Red Empire, Easterners came to Sukhoi. Your order completely saved our Komsomolsk Aircraft Factory and our Sukhoi , Now, your new batch of orders will become another witness of our friendship!" Simonov raised his glass excitedly.

"Yes, we are also very honored. At the beginning, we only relied on the second-generation aircraft to protect the airspace of the motherland. The acquisition of the Su-27 allowed us to have an advanced third-generation aircraft for the first time, with beyond-visual-range air combat capabilities. Now, Although we have more and better aircraft, we will firmly remember the friendship we had back then!" Elder Lin responded.

   "Come on, let's toast together, let's toast to our friendship!"

"We attach great importance to this batch of Su-35 fighters. It makes up for many shortcomings of the Su-27 and is a more advanced heavy-duty air superiority fighter." Lin Lao continued: "This is also important for the development of our aviation industry. There are great benefits."

   Your aviation industry development? Hearing this, Simonov's face suddenly changed. There are many interpretations for this sentence. For example, are the Orientals planning to continue surveying and mapping to imitate their Su-35?

  If the Orientals achieve this goal, can they still sell it?

"Yes, for example, after introducing this fighter, we simultaneously introduced the AL-35F engine, and we will also use this engine on our J-10 fighter, just like the third uncle, our aviation industry We will enter a new page." Qin Tao hastened to speak. These words sounded like they were making up for Mr. Lin. Mr. Lin's words leaked some inside information that shouldn't be leaked!

   Could it be that the Orientals purchased these Su-35s just to imitate the above technology? At this moment, even Simonov's heart began to fluctuate.

  Before the collapse of the Red Empire, there were huge differences in Moscow on whether to export the Su-27 to the East. Many people did not want to export this heavy fighter for fear that it would be imitated by the East.

At that time, Simonov was very confident, thinking that it would take many years for the Easterners to master the production technology of this kind of aircraft. By that time, not to mention the Su-35, the new generation of Sukhoi fighter jets had already taken off. Therefore, It will not pose a threat to one's own side at all.

   But now?

  In addition to producing the Su-27 imitation J-11, the Orientals have also improved the J-15 and are now flying the J-16! This shows that the Orientals have fully mastered the technology of the Su-27! How many years has it been?

Now, the Su-35 is allowed to export. The big reason is that their Sukhoi Design Bureau has started the research and development of the fourth-generation aircraft. However, this research and development has not been smooth sailing, and they themselves will not guarantee that they can master Su- The research and development work was completed before 35 technologies. (The division method of the fifth-generation aircraft should be developed by Lao Maozi. When the West was equipped with F-15 and F-16, Lao Maozi was still using MiG-23 and MiG-25, so it was suppressed by the generation difference Fighting, so the old Maozi was very unwilling, so he positioned the variable-sweep wing fighter like MiG-23 and the double-three fighter like MiG-25 as the third-generation fighter, so that there would be an extra generation. In a certain period Over time, the domestic media has also adopted this classification method, calling our black ribbon the fifth-generation fighter. If the old man talked about the latest fighter, it should be called the fifth-generation fighter. However, in order to avoid readers Great reading confusion, the fourth-generation machine and the fifth-generation machine for a while, and the American classification method will be used uniformly.)

  If they are unlucky and their R&D project fails, wouldn’t the fighter technology of the Orientals be on the same starting line as them?

  Thinking of this, Simonov's face became even uglier.

   Only by exporting the Su-35 can they obtain enough research and development funds to complete the research and development of the fourth-generation aircraft. However, if the fourth-generation aircraft is not successfully developed if it is exported, it will cause more complicated troubles.

  At this time, even Simonov was a little skeptical, wondering if the decision to export the Su-35 would be a mistake.

"The flight performance of the Su-35 we saw today was very good. Most of the performances were performed in the transonic range. The visual flight overload was pulled to 9G. Mr. Pugachev, your technology is definitely the best in the world. "Qin Tao raised his glass and said to test pilot Pugachev.

  This sentence reveals a lot of information!

The second-generation aircraft produced by Dongfang, especially the J-8, have an overload of only four or five Gs. If the overload is too large, the aircraft will definitely disintegrate in the air. The mark of the third-generation aircraft is that it can reach an overload of 9G. Due to the defects of the body structure, the overload is limited to 7.5G in the transonic range.

  Now, the easterners are most concerned about the mobility in this range. What does this mean?

  The Orientals want to solve this problem by introducing the Su-27!

  Pugachev had a smile on his face: "Thank you for the compliment."

  The atmosphere of this dinner party became a little special.

  Eastern people have always been very happy, looking forward to purchasing the Su-35 fighter jets back, which will bring the strength of the Air Force to a new level, but the people in the Sukhoi Design Bureau are not happy at the thought of possible technology leaks.

  This night, many people are destined to have no sleep.

  The banquet was over, and in a certain manor, Grishin came to see the boss with a heavy heart.

Grishin was in charge of the previous international arms sales projects, but staying in one position for a long time will always arouse some suspicions, so this time the arms sales project with Dongfang is not qualified. Rishin's participation.

   Although Grishin did not participate, he also had a say.

   "Do you think, if the Easterners buy back these fighters, how many years will it take them to imitate them?"

   Hearing the boss's question, Grishin thought for a while, and then said, "About five years."

This is already a very conservative estimate. Look at what the Orientals have done in the past few years: quickly grasped the technology of the Su-27, improved the J-15, and are improving the J-16. There is nothing the Orientals cannot do Yes, so, if this plane is sold to the Orientals, it will be found out soon. Five years is the most conservative estimate.

   "Then can we complete the research and development of the fourth-generation aircraft within five years?"

  Grishin thought for a while, then shook his head: "There shouldn't be enough time, after all, we took a detour."

The Mikoyan Design Bureau is still working hard to promote the MiG 1.44 plan. The maneuverability of this aircraft is no problem, but the stealth is absolutely scum. The plasma stealth technology was abandoned after the collapse of the Red Empire. The MiG 1.44 did not Not favored.

The Sukhoi Design Bureau is engaged in the fourth-generation aircraft project, which is interesting. However, this aircraft has just begun to be designed. Unlike Mikoyan Design Bureau, which has been developed for many years, there are still many technical problems waiting to be solved. The research and development time will certainly not be short.

"That is to say, if we export the Su-35 to the East, then we will not be able to gain air superiority over the East for a period of time after that?" The boss stood up: "Then, this deal, we We can't do it anymore, we can't let the Easterners have world-class advanced fighter jets! Inform the Sukhoi Design Bureau and the deal will be cancelled."

   "However, if it is canceled like this, then the Orientals will definitely be unhappy." Grishin was a little worried.

   Isn't this making the Orientals happy? First, the Orientals were asked to buy fighters, and then they stopped selling them!

   "What do you think?" the boss asked.

   "If the fighters are not going to be sold to them, can we sell them the AL-35F engine that the fighters are equipped with?"

   "Of course not, this engine is also the most advanced in our country, so we can't sell it to them!"

   "Then there is only the engine of the Salyut factory. This engine has not been successfully developed yet."

   "This can be sold, let them pay for research and development!"

   PS: 605 has come out, it is exciting and not to be missed, please check back.
